Birds
There are about eight thousand living types, more than 50 percent of which happen to be passerine, or "perching" birds. Birds have got wings whose advancement varies according in order to species; the only known groups with no wings will be the wiped out moa and elephant birds. Wings, which often evolved from forelimbs, gave birds a chance to fly, although further evolution has directed to the loss of air travel in some parrots, including ratites, penguins, and diverse native to the island island species. The digestive and respiratory system systems of chickens are also distinctly adapted for airline flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, possess further evolved with regard to swimming.

According to DNA evidence, modern day birds (Neornithes) progressed in the Middle to Late Cretaceous, and diversified drastically around the time of the Cretaceous? Paleogene extinction event 66 mya, which slain off the pterosaurs and everything non-avian dinosaurs.

Many social kinds give knowledge across generations, which is considered a form of culture. Birds are cultural, communicating with image signals, calls, and even songs, and taking part in such behaviours while cooperative breeding plus hunting, flocking, in addition to mobbing of potential predators. The vast the greater part of bird varieties are socially (but not necessarily sexually) monogamous, usually for one breeding time of year at a moment, sometimes for years, but rarely for life. Other varieties have breeding techniques that are polygynous (one male along with many females) or perhaps, rarely, polyandrous (one female numerous males). Birds produce children by laying eggs which are fertilised through sexual processing. They are typically laid inside a home and incubated by simply the parents. Many birds have an extended period involving parental care right after hatching
